LED globe bulb E27 3W 2,700K with frosted glass for 24V mains voltage This LED globe bulb from Segula's Nautic Line was developed for direct use in a 24V on-board power supply, such as those found in motorhomes, caravans or on houseboats. While a converter is required when using conventional bulbs, this lamp can be used directly. It emits a warm white light colour and can be dimmed. The bulb is equipped with ambient dimming, a function that ensures a decreasing colour temperature during the dimming process (2,700 K - 2,000 K).
